Glycogen is a polysaccharide that is stored in the liver and muscle cells of animals. When glucose, the monomeric subunit found in glycogen, is required for energy, glycogen is broken down through a process known as .

Explanation:

Glycogen is a polysaccharide  that is composed of glucose sub-units. Glycogen  is long polymer and  is mainly stored in liver and muscle cells . When required in energy , Glycogen is broken down into glucose sub-units with the help of various enzymes, and the process of Glycogen broke down  is  known as hydrolysis.

Glycogen is mainly broken down during fast conditions, which full fills the energy  requirement.
